You just adjust your technique. If you rode exclusively high pivots for a while, then hopped on a more traditional design, it would immediately feel very strange the other way too.

My Kavenz has a 1.8 front center/rear center ratio. I’ve also ridden the same bike set up with a 1.93 ratio. The handling characteristics between the two setups is stark. Not as noticeable when it’s super steep but the 1.8 ratio corners way better. Front wheel grip is massively better in flatter corners. The 1.8 ratio setup is also more forgiving of body position and easier to ride fast. I’m firmly in the long chainstay gang at this point.

4/22/2025 8:43am Some complaints about geometry are due to a lack of understanding of packaging constraints. I’m still curious about how these bike designers honestly feel about the compromises between sizes…

Proportional scaling for stack gets really hard with 29 inch wheels on the small side, even on xc bikes running 100mm forks. Having your saddle level with your bars isn't a great indicator of fit either, since it doesn't say anything about your hip handle and hip impingement while pedaling. I'm on the taller side, 6'1 32 inch inseam, and I have always ridden with my saddle higher than my bars because I really like an aggressive seated position on the bike, chest low and forward. Recently, I've been really bringing up my stack height, currently on 35mm of spacers...

My name is Luis Arraiz, I am a frame design engineer and specialize in bicycle vehicle dynamics, kinematics and geometry design. I was the founder of K9 Industries Ltd in 2005 in the UK. I worked at CSG (now Pon) from 2015-2023 where I was responsible for the geometry, kinematics and packaging for all the full suspension bikes both analogue and e-bikes for both Cannondale and GT bikes and also several GT hardtails. I introduced the concept of size specific geometry and kinematics for Cannondale dubbed “Proportional Response”. I am now back to the UK, where I am a senior...

STFU guides. They actually work. They also help with the mythical pedal kickback. External cables with proper guides/clamps. Lastly a silent rear hub. But none of it really matters when you ride solo with earbuds in 90% of the time.

My $8000 bike I bought a year ago with a clutch derailleur still sounds like garbage so I think they still need to work on it.

I did. But I still expect better. We are talking five figure bikes that can be solved with some clamps and mastic tape or a little oval thing. Why is that left to the customers to figure out where it goes?

Some of you never rode when we had no clutches so the loose, flopping chain smashed against every part of your aluminum bike and the fork knocked in the 1 1/8th head tubes and then echoed through your monocoque frame and it shows. I can barely hear my current bike compared to the 3rd grade marching bands on wheels we used to ride pre-2012. I didn't even know you could hear what your tires were doing for the first 10 years I rode.

Not really a tech rumour but a tech wish: since we’ve somewhat stabilized on geo development and are looking at new ways to innovate, can companies put more effort into silencing bikes? It’s kind of embarrassing that a $10k bike sounds like a shopping cart.

4/19/2025 3:13pm One variable we haven’t discussed here is the ratio as it relates to mx vs. full 29. I have a feeling 1.8-1.8? Is ok with 29, but it seems like MX likes that 1.7-1.7? ratio. Anyone have experience with this?

4/19/2025 12:25pm I think you just have to purchase it separately. Maybe don’t tell them what size front triangle you have? I bought my cl stumpy Evo seat stay from a speci shop. They just ordered it as a replacement part.

4/18/2025 11:35pm i have modified my stumpy evo to go from a 1.85 to a 1.75 (approximate, will measure later...) and the difference is huge. I would not have kept this bike if I wasn't able to get it to turn the way I wanted it to. Its amazing that I was able to bolt on the XL seat stay to give...
